タ。 A pair of coating rolls are disposed parallel to each other, and each coating roll is provided with a doctor and a coating liquid supply means, and by passing a substrate between the pair of coating rolls, the coating liquid is passed through the circumferential surface of each coating roll. In a roll coater for double-sided coating that simultaneously applies a coating liquid to both the front and back surfaces of a substrate, the distance between the opposing surfaces of the pair of coating rolls is equal to or less than the thickness of the substrate, and the distance between the coating liquids on the circumferential surfaces of the pair of coating rolls does not come into contact with each other. In order to achieve the above, at least one of the pair of coating rolls is supported so as to be movable back and forth between the two positions, and the coating roll is
A substrate detection means for detecting the presence or absence of a substrate is disposed on the front side in the conveyance direction, and based on a signal from the substrate detection means, the opposite surface of the coating roll is detected during the period when the substrate passes between the pair of coating rolls. so that the distance between the facing surfaces is equal to or less than the thickness of the substrate, and the distance between the opposing surfaces is equal to or greater than the distance at which the coating liquid on the circumferential surface of the pair of coating rolls does not come into contact with each other during a period when the substrate is not passing between the pair of coating rolls.
A roll coater for double-sided coating, characterized by being provided with a drive control mechanism for driving and controlling a coating roll.
